, This invention relates `to locomotive tenders, and more particularly to water bottom frames for such tenders andv to the manner in which feed water is supplied to the locomotive. 4 f

Heretofore water bottom'frames for tenders have been employed in which the water feeding channels or troughs leading-to the front end of the tender have been disposed in level relation to the rails, and in whichthe f thefsame, taken asindicated bythe linesl tank valves, through whichfeed water is `supplied to the locomotive, have been located at the front end of the tender with their intake assages projecting vertically downward l5 rom the water bottom frame. With the use of such constructions,A when the tender .is

standing on a sloping track with its rear end down, it is evident that va considerable amount of water is not available ltothe yinjectors for use in the locomotiveboiler. Furthermore,

on account of the location of the pipes on the `locomotive leading to the injectors, and on vaccount ofthe fact that locomotives are operated over track having considerable curva- 5 ture, it is not practical to move or lower the hoseconnections between such pipes and the tender tank valves.

Accordingly, thev principaly object ofthe present invention is to providel a water bottom tender frame and connections to a locomotive so designed andarranged as to render more water available-to the 'injectors when the tender is on a. sloping'track, without causing the fittings; comprising the connections between the tender tank and locomotive to encroach upon the necessary areas vof clearance above'the track,`and,fthus to overcome the aforementioned difficulties.

im Other more specific` objects and advantages characterizing my invention will become more fully apparent fromthe detailed description of one example or embodiment thereofA which follows hereinafter, having reference to the accompanying. drawings. Ofthe drawings: f c Fig. I yis a side elevation of atender con'- structed in the manner ofmy invention, show.- ing at the front end of the tender the connecting hose leading tothe locomotive and vfront endof the water bottom frame of the `wi th the left-hand `front end chambers ofthe frame,l ythe'manner in which a'tank valve ismount?- edgupon trucks,

VII is a crossfsec'tion of the water bottom" rame, takentransversely ofthe tender lasindicated by the lines'VIIVII of` Fig. 70 i I; and" Fig. VIII is a rear end view of thel water ybottom frame with the right-hand portion shown-in'section as indicated by thelines VIII 'VIII of Fig.v I."l i Wit-h particular referenceto Fig. I tof the drawings, there is shown a locomotive tender similar as to su erstructure `to tenders -now in use and inclu ing'a water space,'designat ed at A, and a coal space/designated at'B, sep- 3 'arated transversely by a slope `sheet 1f'. *It i will be understood,I that, according to'ythe usual practice, the water tank 'delined by the sides of the'tender extends forward in advance of the slope sheet 1 andt-hat the coal` 95 l space B, which 1s at the forward end,` is f lbounded at its sidesabyforwardly extending wings of the water tank. 'Ihewaterk bottom frame, upon which thewater-tank A is vsup- Ported, is comprehen'sivelyv designated at2. 9

Dependin'gfrom'the frame 2 there is shown a water scoop 3 of conventional design. f

yWhile the water tank proper Ais supportthe wheels of which are diagrammaticallyindicated at 11, in parallel:y relation' toth'e rails,it will'y be especially "noted that`v the water bottom: frame `2 slo s down. wardly` towardfthe'front end of t 'e tender, and there terminates in depressed chambers'.

`5 'at eachside ofthe centerline of the tender. la y To the front end chambers 5, tank valves 6 are fitted having the usual hose connections 7 which join the injector feed pipes 8 on the locomotive.

As shown in Figs. II and III, and in the various transverse sections of the water bottom frame 2 of the remaining figures of the drawings, the frame 2 is made up of a single casting including a center sill member 9, holsters 10 and 11, end sills 12 and 13, and side channels or troughs 14. The construction of the center sill member 9, as well as that of the holsters 10, 11 is generally similar to that of tender frames now in general use, and, therefore, need not be described in detail.V At ythe forward end of the tender, the center sill member 9 terminates in a wearing plate 15, and is formed adjacent theretol with a fulcrum pin housing 16 of common construction. The usual center plate 17 for the forward truck is provided at the point where the center sill member 9 joins t-he front end bolster 10, as shown in Figs. IV and V, and a similar center plate 18 for the reary truck is formed at the rear bolster 11, as shown in Fig. VIII. The web portions 19 and20 of the front and rear holsters, respectively 10 .and 11, merge at their outer ends with the side channels 14.` The side-channels 14 extend from one end of the tender to the other and are. depressed below the other l portions of the water bottom frame 2.

j At the front end of the water bottom frame 2, as shown in Fig. III, flat plate-members vto 21 and 22 are forme-d integral with the frame between the center sill 9 and the side channels 14, the plate members 21 and 22 serving as the bottom ofthe water tank at that region of thetender. The side channels 14 merge with the front end sill 12 forming the chambers 5 which are directed diagonally inward toward the center line of the tender. At each side of the center sill 9, the framez 2 is formed with upstanding flanges 23 to the marginal edges of which there are riveted the plates which comprise the sides ofthe coal space B. The iioor of the coal space l5 is -indicated at 24 in Fig. I.

At the rear end ofthe tender and vat the intermediate portion. the water frame 2 has cast integral therewith flat plates. such as designated at 25 and-2G in Fig. VII, which form the bottom of the water tank in these regions. Upstanding projections, such as shown-at 2T and 28, on the flat plates and 26, serve as attachments to which vertical tank braces are anchored. l

Throughout the length of the tender, side lates 29 are riveted to the vertical flanges 30 of the side channels 14. In the present example of the invention, the cross-section of each side channelllA changes in form from one region of the vframe 2 to another, as illustrated in Figs. IV, VII and VIII. The bottom members 31 of theside channels 14 are flat continuous plates sloping with gradual inclination from the rear of the tender toward the front end. At each transverse section of the frame, the bottom members 31 of the side channels 14 represent the lowest points of the water carrying space of the' tender; and the front end chambers 5, to

which the side channels 14 lead, are still further depressed, and constitute the parts of the water bottom frame which are nearest to the rails. It will be particularly noted that, while the side channels 14 slope down- Ward toward the front end of the tender, the center sill member 9 is supported on the tender trucks in parallel relation to the rails and the various plates 21, 22, 24, 25, 26, which form the major portion of the tank bottom, are likewise parallel to the rails. rfhus the side channels 14 serve as water feeding troughs, rendering more water available to the locomotive injectors when theftender is standing on a sloping track with the rear end down, but the side channels are so formed with respect to the remainder of the water bottom frame as not to require a material departure from standard practice with regard to the general construction of the frame.

In Fig. VI there is shown an enlarged sectional view of one of the tank valves G lothe manner in which the valvclis applied to a front end chamber 5 which forms the terminus of the lCorrespending side channel 14. At the bottom of each chamber 5, a threaded plug 32 is screwed intoa correspondingly threaded opening and serves as a means of rendering ready access tothe chamber for the purpose of draining or washing out the chamber. The tank valve as represented in the present example of the invention, is a valve of ordinary construction comprising a valve member 33 seated 4within the intake passage 34 and operated through an operating shaft 35 and a handle 36. IVhen the handle 36 is turned to engagement with a pin 3T, water flows in the direction indicated by the arrow through the intake passage 34, and the discharge passage 33 to the flexible hose 7, and from thence to the injector feed pipes 8 on the locomotive.. A screen 39 is preferably provided within each chamber 5 at the point where the tank valve 6 is fitted thereto. In contriulistinction to the usual practice of applying a tank valve to a water bottom frame with the intake passage disposed vertically beneath the end of the frame, the tank valve G of this invention is applied with its intake passage 34 disposed in a horizontal plane. .Accordingly, though the vertical distance between the bottom of each chamber 5 and the top surface of the rails has been lessened by the downward sloping of the side channels of the frame, the

hose connections 7 are still maintainedat the customary height above the rails.

From the above description it will be apparent that the novel design of the water bottom frame of this invention with its forwardly and downwardly sloping side channels 14 and the novel manner in which the tank valves are applied to the front end of the frame overcome difficulties characteristic of older constructions, occasioned when a tender is on an upgrade, and result in more water being available to the locomotive injectors without lessening the clearance between the bottom of the tender frame and the underlying track.

While I=have described one form or eX- ample which my invention may take and have referred to certain specific features of construction, it will be apparent that various changes may be made in the particular form of tender herein selected as an example of the ractice of the invention, without departing from the spirit of the invention as defined in the annexed claims.

Having thus described my invention, I claim:

l. In a locomotive tender, a frame including a water bottom sloping downward toward the front of the tender throughout substantially the length thereof.

2. In a locomotive tender, a tank, and a frame for supporting said tank in parallel relation to the rails, said frame including a water bottom sloping downward .toward the front of the tender throughout substantially the length thereof.
